"None",
"7 sec.",
"6 sec.",
"9 sec."
] | C | Solution
Speed of the train relative to man =( 68 - 8 )
= 60 Kmph

=50/3 m/sec.
Time taken by it to cover 100 m at (50 /3)m/sec
= (100 x 3/50)sec
= 6 sec.

A quadratic function f(x) attains its minimum value of -15 at x=3. If f(0)=5, find the value of f(9). | [
"65",
"55",
"-25",
"25"
] | A | Explanation :
Any quadratic equation can be written as f(x) = α(x-k)2 - β
Given that minimum value of f(x) is -15 at x=3
f(x) is minimum when x=k => k=3
-15=-β => β= 15
Also given that f(0) = 5
=> 5 = α(0-3)2 - 15 => α= 20/9
Hence, f(9)=20/9(9-3)2 - 15 = 65

] | D | D
24miles/hr (not 25miles/hr which might be guessed by many)
D : distance traveled
T1 : time of going to office
T2 : time of returning back
Y : Average Speed
D = 20 * T1
T1 = D/20
D = 30 * T2
T2 = D/30
2D = Y(T2 + T1)
2D = Y(D/20 + D/30)
2D = Y(3D/60 + 2D/60)
2D = Y(5D/60)
Y = 120D/5D
